Automatic Tunable Laser System in Littman/Metcalf Configuration

Sacher Lasertechnik has introduced a new generation of automatically tunable laser system in Littman/Metcalf configuration.The laser systems offers a high output power, typically 500 mW,over a large tuning range with complete user remote control. 

Features include: 
         

·        Excellent tuning behavior

       -- coarse and fine- tuning modes

       -- fine tuning via piezo actuator with a resolution of 10MHz

       -- coarse tuning via DC servo motor up to 25 nm at 780 nm

       -- large mode-hop free tuning range of up to 30 GHz and more

·        Narrow linewidth

       -- linewidth < 500 kHz

            excellent side mode suppression >50 dB

       -- high-flexibility

            systems with wavelength of 760 to 1080 nm are available, further wavelengths are under development

       -- free beam and fiber-coupled versions available

            constant current and constant power operation modes

       -- Plug & Play configuration

       -- automated wavelength tuning with wavelength and power readout

       -- remote control via GPIB, RS232 and USB

Applications for the new laser generation include:

·          Spectroscopy and optical process control

·          Optical cooling and trapping, BEC

·          Absolute-distance interferometry

·          Laser and OPO seeding

·          Nonlinear optical processes

·          Characterizing of fiber optical systems
